SCREEN FRAME.

To all whom it may concern:

Be'it known that I, FRANK MUsHALL, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Screen Frames, of which the following is a full, clear, and exact description.

My invention relates to screen frames, and

consists in the combinations, constructions and arrangements herein described and claimed.

.Anobject of my invention is to provide a screen for a window or the like,in which the frame may be fitted into various sizesof window casings.

A further object of my invention is to provide a screen, having a frame which may be placed in a window casing, and in which any play between the frame and the casing is automatically taken up, thus preventing rattling of the screen.

A further object of my invention is to provide a device of the character described, which is durable and which is thoroughly effective for the purpose intended.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a front elevation of one embodiment of my invention,

Figure 2 is a sectional view along the lines 2-2 of Figure 1, and

Figure 3 is a sectional View along the lines 3 -3 of Figure 1.

In carrying out my invention, I provide a quadrangular frame 1, in which a screen 2 is supported by means of beading 3. One end of the frame 1 has secured to it by means of screws 4 a substantially rectangular metal plate 5 which extends from one side of the frame to its opposite side. y

i The plate 5 is provided with four slots 6, as shown in Figure 1. A wooden cross piece 7, having four flat headed screws 8, each of which screws is arranged to register with one of the slots 6, is placed in parallel relation with the plate 5. The wooden piece 7 is substantially the same width as the material of the frame 1. This is clearly shown in Figure 2. At the opposite side of the wooden piece 7 are two T-shaped metal Specification of Letters Patent.

members 9 extending upwardly therefrom and secured at their lower ends by means of screws 10 to the wooden piece 7. The metal members 9 are provided with longitudinal slots'll. A pair of flat headed screws 12 are disposed onthe opposite side of the lower end of the frame 1 and arranged to register and engage the slots 11, so that the metal members 9 may slide in a way to limit the longitudinal movement of the members 9 carried by the transverse wooden piece 7. Two vertical screws 13 are disposed upon the upper surface of the wooden piece 7 and extend up through an opening. 14 in the lower end of the frame 1. compression spring 15 is disposed concentric each of the screws 13, and is arranged to bear against the lower piece 7 in a manner to normally force these two members apart. I I

To provide against flies and mosquitoes from entering through the screen, transverse metal flaps 16 are pivotally mounted upon the screws 8 intermediate the plate 5 and the transverse wooden piece 7, and a groove 17 is provided in the adjacent surface of the lower end of the frame 1 to permit the entrance of the stop 16 when the wooden piece 7 is forced up toward the framel, as in fitting the screen to a narrow window. Handles 18 are provided on the inner surface of the frame 1, so that the screen may be easily handled.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. Assuming that the screen is to be used for a window, and it is found that the window is not exactly the length of the screen. If the ordinary screen were to be used, it would have to be cut down, while in the present case, I

have provided a screen having a wooden piece 7 which is arranged to move toward the frame 1 against the action of the screws 15, and thus actually contract the length of the screen as awhole.

lVhen the screen is thus fitted to a window casing, it will be tightly held in place, since the action of the springs 15 constantly tend to force the frame 1 and the wooden piece 7 away from one another, and thus will cause the close engagement of the screen with the window casing.

A further advantage is that if the sides of the window casing to which the screen is to be applied are not parallel, the yielding Patented Aug. 29, 1922. Application filed November 12, 1921. Serial No. 514,677.

end of the frame 1 and the wooden outer edge of said frame,

portion 7 of the screen will take up any such variation and fit snugly and tightly in the casing. This is not true of the ordinary type of window screen.

I claim: 7

l. A device of the character described comprising a frame for supporting a screen or the like, a rectangular plate carried at one: end of said frame, of substantially the same length thereof and arranged to overlap the'outer edge of said frame, said plate having a plurality of transverse slots therethrough, a movable bar disposed adjacent one side of said frame, a plurality of screws provided on said bar and arranged to register wlth and extend through said slots through said plate, said screws having enlarged heads for preventing said screws from coming out of said slots, and compression spring means for normally holding said bar away from said frame.

2. VA device of the character described comprising a frame for supporting a screen or the'like, a rectangular plate carried at oneend of said frame substantially the same length thereof, and arranged to overlap the said plate having a plurality of transverse slots therethrough, a movable bar disposed adjacent one side of said frame, a plurality of screws carried by said bar, and arranged to extend one through each of said slots in said plate, said screws having enlarged heads thereon for prevent ing said screws for moving out of said slots,

a plurality of compression springs disposed intermediate said frame and said bar, and a plurality of flaps each of which is secured at one end to one of said screws for closing the opening left by said slots.

3. A device of the character described comprising a frame for supporting a screen or the like, a rectangular plate carried at one end of said frame substantially the same length thereof, and arranged to overlap the outer edge of said frame, said plate having a plurality of transverse slots therethrough, a movable bar disposed adjacent one side of said frame, a plurality of screws carried by said bar, and arranged to extend one through each of said slots in said plate, said screws having enlarged heads thereon for preventing said screws for moving out of said slots, a plurality of compression springs disposed intermediate said frame and said bar, a plurality of flaps each of which is secured at one end to one of said screws for closing the opening left by said slots, a plurality of metal flaps having transverse slots therethrough secured on said bar onthe opposite side from said screws on said bar and arranged to extend upwardly and contact the adjacent side of said frame and large headed screws provided on said adjacent side of said frame adapted to be in register and pass through said slots in said second named plates.
